Rewrite the following nested if-else statement as a switch statement that accomplishes exactly the same thing. Assume that num is an integer variable that has been initialized, and that there are functions fl, f2, f3, and f4. Do not use any if or if-else statements in the actions in the switch statement, only calls to the four functions. if num < -2 || num > 4 f1 (num) else end if num <= 2 end if num = 0 f2 (num) f3 (num) else else end f4 (num) Test your switch statement with num: a random integer from -5 to 5, and creating anonymous functions for fl-f4: fl=sin²(num), f2=e" ¹ cos(num), f3= num³+2*num, f4= arctan(num). num
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
